In any case in which:
A. it is desired to remove, lower or otherwise terminate a nonconforming use; or
B. the approach protection necessary according to the legislative body's airport approach plan cannot, because of constitutional limitations, be provided by airport zoning regulations under the Municipal Airport Zoning Law [ 3-39-16 to 3-39-26 NMSA 1978]; or
C. it appears advisable that the necessary approach protection is provided by acquisition of property rights rather than by airport zoning regulations, the political subdivision within which the property or nonconforming use is now located, or the political subdivision owning the airport or served by it, may acquire, by purchase, grant or condemnation in the manner provided by the law under which political subdivisions are authorized to acquire real property for public purposes, such an air right, easement or other estate or interest in the property or nonconforming use in question as may be necessary to effectuate the purpose of the Municipal Airport Zoning Law.
